Canadian police say the whereabouts of a suspect in a deadly stabbing rampage remains unknown, urging the public to take appropriate precautions after earlier warning residents of an Indigenous reserve the suspect may be nearby.
Two brothers were accused of killing 10 people and wounding 18 in the weekend attacks in the central province of Saskatchewan.
On Tuesday, Canadian police officers surrounded a home with guns drawn on an Indigenous reserve where the stabbing rampage took place.
Police sent an emergency alert to phones asking people on the James Smith Cree First Nation reserve to stay inside. Witnesses said people ran screaming as police shut down roads.
Later on Tuesday, an official familiar with the matter said it appeared to be a false alarm. The official spoke on condition of anonymity as they were not authorised to discuss the matter publicly.
It's not clear if the suspect, Myles Sanderson, was ever in the area.
The fugitive's brother and fellow suspect, Damien Sanderson, 31, was found dead on Monday (local time) near the stabbing sites.
Police suspect that Myles Sanderson, 30, killed his brother.
Assistant Commissioner Rhonda Blackmore said police were still determining the motive.
Ms Blackmore said the criminal record of Myles Sanderson dated back years and included violence.
Last May, Saskatchewan Crime Stoppers issued a wanted list that included him writing that he was "unlawfully at large".
Before Damien's body was found, arrest warrants were issued for the suspects and both men faced at least one count each of murder and attempted murder.
Drugs and alcohol blamed
Leaders of the James Smith Cree Nation, where most of the stabbing attacks took place, blamed the killings on drug and alcohol abuse plaguing the community, which they said was a legacy of the colonisation of Indigenous people.
The chief of the Federation of Sovereign Indigenous Nations echoed suggestions the stabbings could be drug-related.
"This is the destruction we face when harmful illegal drugs invade our communities, and we demand all authorities to take direction from the chiefs and councils and their membership to create safer and healthier communities for our people," Chief Bobby Cameron said.
James Smith Cree Nation resident Darryl Burns and his brother, Ivor Wayne Burns, said their sister, Gloria Lydia Burns, was a first responder who was killed while responding to a call.
Mr Burns said his 62-year-old sister was on a crisis response team.
"She went on a call to a house and she got caught up in the violence," he said.
"She was there to help. She was a hero."
He blamed drugs and pointed to colonisation for the rampant drug and alcohol use on reserves.
"We had a murder-suicide here three years ago. My granddaughter and her boyfriend," Darryl Burns said.
"Last year we had a double homicide. Now this year we have 10 more that have passed away and all because of drugs and alcohol."
Ivor Wayne Burns also blamed drugs for his sister's death and said the suspect brothers should not be hated.
"We have to forgive them boys," he said.
"When you are doing hard drugs, when you are doing coke, and when you are doing heroin and crystal meth and those things, you are incapable of feeling.
"You stab somebody and you think it's funny. You stab them again and you laugh."
'I'm hurt for all this loss'
The stabbing attack was among the deadliest mass killings in Canada, where such crimes are less common than in the United States.
Police in Saskatchewan got their first call about a stabbing at 5:40am on Sunday, and within minutes heard about several more.
In all, dead or wounded people were found at 13 different locations on the sparsely populated reserve and in the town, Ms Blackmore said.
Among the 10 killed was Lana Head, who is the former partner of Michael Brett Burns and the mother of their two daughters.
"It's sick how jail time, drugs and alcohol can destroy many lives," Mr Burns told the Aboriginal Peoples Television Network.
"I'm hurt for all this loss."
Weldon residents have identified one of the dead as Wes Petterson, a retired widower who made coffee every morning at the senior centre.
He loved gardening, picking berries, canning and making jam and cakes, recalled William Works, 47, and his mother, Sharon Works, 64.
"He would give you the shirt off his back if he could," William Works said, describing his neighbour as a "gentle old fellow" and "community first".
Sharon Works was baffled: "I don't understand why they would target someone like him anyway, because he was just a poor, helpless little man, 100 pounds soaking wet.
"And he could hardly breathe because he had asthma and emphysema and everybody cared about him because that's the way he was.
"He cared about everybody else. And they cared about him."
